Color Scheme

Sequential color schemes are good for focusing attention on areas of high rates and for maps that might be printed in black and white. They are based on a single hue with lighter colors for areas with low rates and more intense colors for areas with high rates. Sequential schemes do not support more than 9 intervals. Different data topics use different color schemes.

Additional Information About Color Schemes

The color schemes for this section of the web site have been chosen from the schemes that were developed by Dr. Cynthia Brewer and can be found at: ColorBrewer2.org. The individual RGB or HTML color codes are available on the ColorBrewer web site. These color schemes have been tested for use with printers, monitors, and color blind users.
